Meet Yoko Iwamoto

Meet Yoko Iwamoto

  Water is an all-encompassing part of Yoko Iwamoto’s life. She grew up by the sea, influencing her decision to study the ocean. Her studies have taken her as far north as the Bering Sea and as far south as the Equator. Now a marine chemist at Hiroshima University, Iwamoto studies the interaction between Earth’s… Read more

Well-wrapped feces allow lobsters to eat jellyfish stingers without injury

Well-wrapped feces allow lobsters to eat jellyfish stingers without injury

[su_youtube url=”https://www.youtube.com/watch?v=BuVvfpIBvY0″ width=”660″] Results advance efforts for sustainable lobster aquaculture Lobsters eat jellyfish without harm from the venomous stingers due to a series of physical adaptations.  Researchers from Hiroshima University examined lobster feces to discover that lobsters surround their servings of jellyfish in protective membranes that prevent the stingers from injecting their venom.  The results… Read more

Potential of disk-shaped small structures, coccoliths

Potential of disk-shaped small structures, coccoliths

To promote efficient bioenergy production Researchers at Hiroshima University and the University of Tsukuba showed that coccolith disks made of calcium carbonate in Emiliania huxleyi, one of the promising biomass resources, potentially perform roles in reducing and enhancing the light that enters the cell by light scattering. Elucidation of the physiological significance of coccolith formation in E…. Read more

How many organisms do live in this aquatic habitat?

Environmental DNA survey surrounding you     The aim of this new measurement method is to estimate the distribution of aquatic animals using droplet digital polymerase chain reaction (ddPCR) in order to quantify the number of target DNA copies present. This method focuses on quantification accuracy for low environmental DNA (eDNA) concentrations, because the eDNA… Read more
